It is but you cant. that's why they say tell the customer the code is 0xxxx then it will always clear previous keypresses on use.

It was annoying when you couldn't end with a 9

Does this not drop it below the 10000 required codes on the current keypad matrix ?

what 10000 codes?

Thinking out aloud,

 

Thats the code maximum on a 10 digit keypad. With a 4 dig code

I must admit a thought the 10000 minimum was based on differs for keys, logical keys and mechanical. But it appears a code is classed as a logical key.

I did raise this when we started using them and use a 5 or 6 digit code now.

without a 0 there are only some 6 odd thousand combinations if using 4 digits

That was my point.

I recall somewhere in the dim past something about the 10000 being needed to pass some reg or another.

 

Key differs are "different" and were lower with Chubb locks but Euro Cylinders and the like have upped this to a more acceptable level.
